Surgical site infection is a frequent complication after elective colorectal resection.
The National Nosocomial Infection Surveillance system surveys all colorectal surgeries together.
However, the surveillance system does not differentiate the type of colorectal surgery performed.
|Infection rates in colon vs rectal surgeries were 9% and 18%|

Rectal surgery may have a higher risk for surgical site infection.
Identifying risk factors that are more specific to each procedure would be more predictive.
Dr Tsuyoshi Konishi and colleagues investigated the incidence and risk factors of incisional surgical site infection in elective colon and rectal surgery.
The investigative team conducted a prospective surgical site infection surveillance of elective colorectal resections.
The team evaluated the resections performed by a single surgeon in a single institution from 2000 to 2004.
The investigators collected the data for colon and rectal surgeries separately.
The outcome of interest was incisional surgical site infection.
Univariate and multivariate analyses were performed to determine the predictive significance of variables in each type of surgery.
A total of 556 colorectal resections, consisting of 339 colon and 217 rectal surgeries were admitted to the program.
The investigators found that the incisional surgical site infection rates in colon and rectal surgeries were 9% and 18%, respectively.
Risk factors for developing incisional surgical site infection in colon surgery were ostomy closure, and lack of oral antibiotics.
The team noted that in rectal surgery, risk factors were preoperative steroids, preoperative radiation, and ostomy creation.
Dr Konishi's team concludes, “Colon and rectal surgeries differ with regard to incidence and risk factors for developing incisional surgical site infection.”
“Surgical site infection surveillance for such surgeries should be performed separately.”
“This should lead to more efficient identification of risk factors and a reduction in surgical site infection.”
